How many are supposed to be bolts and how many are studs? From the looks of the evo x o2 housing i recieved...2 studs and rest are bolts? studs wont work for the rest of the holes...holes are too big. Also does anyone know the part # for the o2 to downpipe gasket? my o2 housing didnt come w/ one :/

 

nm its late and im slowly growing more retarded as the hours pass on

 

on the X housing I believe there is only 1 bolt nut combo, the rest are studs coming off the hotside.
